The invention consists of it casing having at nted therein and pro vided with it series of numerals deposed in a circle and adopted to be successively exposed through on opening in the casing. 'l he disk has concentric series of inpertures within it adopted to be engaged by a pencil or other pointed object, so es to rotate the disk n. desired distance in order to bring the proper numeral in position beneath the opening. An. indicator is actuated by the rotation ol the disk for desiginning hundredn, while the disk is utilized for designating tons and units.

The invention also consists of curtain other novel features of eonst ruetiou and combinations of ports, whieh \riil he hnreinri tor more fully described, and pointed out in tluw-laiins.

A sleeve having an internally-tbreaded end is arranged on the serew 1'7 and has n slot. 23 extending longitudinally thereof. Gradt' etions are arranged along the edges of the slot, as shown at 24, and are llesi dlflled lil Clltll'tlCiOlS indicating hundreds/ into the slot 23 projects an Index in the form of a. pin 25, which is supported pandlel with the eover t) by a standard 12o, 'liXttll seoured on the cover, said stnndmd bovine apertures in which the pin is A stop-pin 27 extends hangs down within the posit irely liinitltho lonol the pin 25 endcprerent it from being it it hdraxrn l'roni thestundard so, and a U-shaped spring 28 is inter posed he! r ll the pin 25 and the standard t0 exert a vonstnnl pressure on said pin and to hold it in an) position to which it may be adjusied.

l l t; is thought that the advantage in having;- several rows of apertures exposed throu h the opt-nin 11 will be apparent from tie 'loregoin (escription. The aperture serves as a guit e the movement of the l for limiting l inserted pencil and the disk, and therefore by placing the pencil against one end of the 1 opening it and within thelust aperture in the 3 column the disk can onlybe l l rotated three spaces. By placing the encil in the end aperture in the 5 column tli be rotated five spaces, &c. While only four series of apertures have been designated, the same a )pearin in the 3, 5, .7, and 9 columns, it is to be understood that, if l e disk can only desired, a number ofseries of openings may be employed suflicient to provide nine rows instead of four, as above designated. By la-r opening for limiting the pencil no particular providing an irre the movement 0 skill must be exercised in rotating the disk a 1 predetermined distance to cause the proper number to be indicated. It is merely necessnry to move the pencil as for as it will go, i whereupon a correct number will appear in the opening 10.

said tuVtt having characters thereon desig.

, crture l'or successively disclosing the characlOC holdi ters upon the disk, and means carried by the casing for indicatin the number of rotations of the disk, the wiillsof the 0 ening in the cover constituting stops for a isk-operating device. i

3. The combination with a casing having an aperture therein; 01" a numeral-carrying disk rotatably mounted within the casing, sa pear within the aperture, a screw fixed to and rotatable with thedisk, a graduated sleeve engaging and movably mounted on the screw, and an index for holding the sleeve against rotation, -said index ada ted to cooperate with the graduations to in icate the rotations of the disk.

an index longitudinally movable within the standard and normally projecting into the slotted sleeve said index adapted to prevent rotation of the sleeve and tocooperate with ,its graduations to indicate the number of revolutions of the disk.

7. The combination with a casing having an aperture therein; of a numeral-carrying disk rotatably mounted within the casing, said numerals adapted to successively appear within the a ertui'e, a screw fixed to and rotatable with tie disk, a graduated sleeve engaging and movably mounted on the screw, and an index outside of and detachably engaging the sleeve for holdin said sleeve against rotation, said index' adapted to cooperate with the graduation to indicate the rotations of the disk.
